PhD student (m/f/d)

Tätigkeitsprofil:

The Max-Born Institute invites applications for a PhD student (f/m/d) for the joint German-French project “FEMTO-switch” on ultrafast dynamics of photoswitches funded jointly by DFG and ANR. The main objective of FEMTO-switch is to establish rational grounds as to how the chemical structure of ultrafast photo-switches controls the molecular energetics and excited state dynamics of ultrafast photo-switches at the conical intersections. To this end, we will employ femtosecond UV/VIS/NIR and photoelectron spectroscopy (fs-PES) in the liquid phase, coupled to quantum chemistry calculations. The advertised position is for the experimental research using femtosecond photoelectron spectoscopy in liquids.

Project objectives: Development of time-resolved photoelectron spectroscopy (TRPES) in the liquid phase with UV pump and XUV probe in application to samples of biomimetic chromophores at low concentrations. Investigation of oxindole-based and oxopyrrole based chromophores.

Expected results: Improved sensitivity and stability of TRPES for different solvents and solutes of low solubility. Experimental protocols for biomimetic samples. Experimental and theoretical investigation of oxindole switches (in collaboration with project partners). Dynamics of novel biomimetic switches developed in FEMTO-switch.

Techniques to be used: Time-resolved photoelectron spectroscopy in liquid phase using femtosecond XUV pulses.

Anforderungsprofil:

We are seeking highly motivated, talented, and excellent candidates for this position. Applicants must hold a Master’s or Diploma degree in chemistry or physics, with good knowledge in femtosecond molecular dynamics and ultrafast laser physics. Prior experience in ultrafast spectroscopy would be an advantage. Very good verbal and written communications skills in English are required.
